My understanding is 1> if an SDP offer received in a SIP request, such as all media streams in the SDP offer, => the SDP answer is returned in a 488 Not Acceptable Here response and a SIP607 log is generated.
2> If an SDP offer received in a provisional response, such as all media streams in the SDP offer, => it must be rejected, the SDP answer is returned in the PRACK. Now an new SDP offer is received in a provisional response, 180 Ringing, then the switch should reject the SDP offer in PRACK. Do you think it is right? Thanks.
